SIP protocol has the advantages of simple structure, easy to expand, and so on.It has a good development prospects in network integration and business integration.Now many large business providers have begun to deploy and operate SIP based fixed network VoIP business, SIP will increasingly become the dominant voice communications.In this paper, we first introduce the architecture of VoIP system, secondly we introduce the VoIP two application layer control protocol, H.323 and sip, finally introduces the SIP messages and signaling interaction process.In order to further understand the SIP message and the signaling interaction process, this paper designs a message sending and receiving module based on SIP protocol.Java language and SIP has good compatibility, so we choose Java language, and achieve it through an interface and two classes.A single user and multiple users can send and receive a simple message ultimately.
